Gradients, Poisson's Equation and Light Transport | Two Minute Papers #20

Photorealistic rendering (also called global illumination) enables us to see how digital objects would look like in real life. It is an amazingly powerful tool in the hands of a professional artist, who can create breathtaking images or animations with. However, images created with these technique contain a substantial amount of noise until a large number of light rays are computed. Today, we're going to talk about how to use gradients and Poisson's equation to speed up this process substantially. ________________________ The paper "Gradient-Domain Path Tracing" is available here: https://mediatech.aalto.fi/publicatio...
